The current was setting hard in Germany against the Reformed religion and against the Netherland cause, the Augsburg Confessionists showing hardly more sympathy with Dutch Calvinists than with Spanish Papists.
Envoys from Don John also attended the diet, and requested Saint Aldegonde to furnish them with a copy of his oration.

This he declined to do.

While in Germany, Saint Aldegonde was informed by John Casimir that Duke Charles of Sweden, had been solicited to furnish certain ships of war for a contemplated operation against Amsterdam.

The Duke had himself given information of this plot to the Prince Palatine.

It was therefore natural that Saint Aldegonde should forthwith despatch the intelligence to his friends in the Netherlands, warning them of the dangers still to be apprehended from the machinations of the Catholic agents and functionaries in Amsterdam; for although the Reformation had made rapid progress in that important city since the conclusion of the Satisfaction, yet the magistracy remained Catholic.
William Bardez, son of a former high-sheriff, a warm partisan of Orange and of the "religion," had already determined to overthrow that magistracy and to expel the friars who infested the city.
